Metal Gear Solid Peace Walker PSP

Metal Gear Solid: Peace Walker (メタルギアソリッド ピースウォーカー Metaru Gia Soriddo Pīsu Wōkā?, commonly abbreviated as MGS PW) is a game in the Metal Gear series. It was released for the PlayStation Portable in 2010. It explains the story of Big Boss and leads up to the events of the founding and the creation of Outer Heaven. The game was officially announced at Sony's E3 press conference on June 2, 2009. Hideo Kojima designed, wrote, produced and directed the game. The theme song for the game is titled "Heavens Divide." To reflect the different gameplay style, the series tagline "Tactical Espionage Action" was replaced by "Tactical Espionage Operations." The game's development was done in memorandum to Satoshi Itō, a.k.a. Project Itoh, the author of the Metal Gear Solid 4: Guns of the Patriots novelization, who had died from a battle with terminal cancer a year before the game was released.

The game is set in 1974, ten years after the events of Metal Gear Solid 3: Snake Eater, four years after the events of Metal Gear Solid: Portable Ops, and just two years after the events of the Les Enfants Terribles project. The setting of the game takes place in Costa Rica.

The game was released in Japan on April 29, 2010; North America on June 8, 2010; Europe on June 17, 2010; and the UK on June 18, 2010. On a related note, this was the first time a Metal Gear Solid game was released in Japan first instead of overseas first/internationally since the first Metal Gear Solid.

On November 8, 2011, Peace Walker was re-released as a component of the international versions of the Metal Gear Solid: HD Collection for both the PlayStation 3 and Xbox 360.
